Detail

Description:
1. TPA3255 is a high-performance class D power amplifier, it has class D efficiency and can bring true high-end sound quality. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath Ultra HD).

2. This technology allows the device to maintain ultra-low distortion throughout the audio frequency band while exhibiting perfect sound quality. The device works in AD mode. When the THD is 10%, it can drive up to 2 315W/4R loads and 2 150W (unclipped power)/8R loads, and has a 2 VRMS analog input interface that supports high-performance DAC (For example, TI's PCM5242) seamless connection.
3. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power level idle loss (less than 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver scheme. Compared with the traditional discrete implementation, this solution can significantly reduce idle loss.

Specification:
Working mode: Level D
Standby current: 80mA
Work efficiency: > 90%
Channel: 2.0
Rest / mute: short circuit mute function
Output power:
315W/ 4 Ω, distortion 10%

260W / 4 Ω, distortion 1%
150W / 8 Ω, distortion 1%
Frequency response: 20Hz to 20KHz
Dynamic range: > 100 dB
Signal to noise ratio: (SNR) > 111db
Working voltage: dc24-40v switching power supply (recommended voltage: 36V)
Product size: 110 * 70 * 36.5mm
Product weight: 160g

Product details:
1. Use original TPA3255
2. The computing end uses the replaceable DIP-8 op amp *2, and buyers can upgrade the computing model independently. This product uses 2 TI high-performance audio operational amplifiers NE5532P
2. The main filter electrolytic capacitor adopts Nichicon capacity 2200UF/63V*2, 6 Nichicon FW series 10UF golden audio input coupling capacitors. Other filter capacitors use Nichicon series.
3. Adopt SAGAMI 7W14A inductor for audio digital class D amplifier to ensure the sound is clear and powerful.

Package included:
1* Power amplifier board
1* Signal line
